BY MnsNn AssiGNMEN'rs, To THE NATIONAL CASH REGISTER COMPANY, OF DAYTON, OHIO, A CORPORATION OF MARY- LAND CASH REGISTER Application led September 25, 192,2. Serial No. 590,371.

This invention relates to cash registers, and particularly to improvements in the type of machine shown in applicants co-pending application for Letters Patent of the United States, Serial No. 293,141, filed April 28,

One of the objects of this invention is the provision of mechanism for carrying out the process of multiplication and for indicating the multiplicand and multiplier.

It is alsoan object to provide mechanism for accumulating the items of a transaction, for printing the total of the items, and for indicating the number of items entered at any time prior to a total printing operation.

Special objects of this invention are to carry out these provisions in connection with the type of register shown in said application; to employ the regular indicating mea-ns for indicating the multiplicand; to provide special indicating means only for the multiplier; to operate the special indicating means during each operation of the item entering means; to turn said special indicating means to zero during each total-taking operation; and to provide means for shifting the totalizer and its actuators relatively laterally to enter the amounts represented' by the keys depressed in the proper totalizer wheels in processes of multiplication.

With these and incidental objects in View, the invention consists of certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims, and preferred forms or embodiments of which are hereinafter described with reference to the drawings which accompany and form part of this specification.

The embodiments illustrated inclu e the usual amount keys, means for indicating the amount set up on the keys, means for entering said amount in a totalizer and for printing the same, and means for printin the total of amounts entered. In addltion, mechanism is provided for shifting the totalizer and actuators relatively laterally or selectively rendering totalizer actuators effective and ineffective, for carrying out processes of multiplication by successive addition, and means for counting the number of items in a transaction and igor setting up a multiplier in carrying out processes of multiplication.

In the embodiments illustrated, having particular reference first to Figs. l to 13, keys 30, arranged in denominational groups vic as usual, are lpivoted on a transverse rod carried by the side frames of the machine, and at their rear ends are notched to cooperate with a lip on a key coupler 31 for purtaneous depression of a. plurality of keys in VtotaliZier actuator 39 is directly secured tol the rocker framewhich is free on said: shaft 38. The Adimes totalizer actuator "39 and rocker-'frame are-secured to said shaft 323',y asshown in Fig. .1. Thenotchesin; the actuator controllers 34are'located toftransmit, amountsV ofV movement. to the actuator pro-Y portionatevto the number of units represented by the keys-'30 to Whichthe .actuator controllers-are connected. j Y l The totalizer` actuators-39 are normally in mesh. with gears: 40 Which vare, connected with thelitem typevvheels 41 (Fig. 13)l by. a tube line.42'(Fig. 1)f to set up the amounts represented by the keys depressed.

The key coupler 31, (Figs. 1', 2 and 8)..bef forereferred to,is pivotally mounted inthe side framesand rests-.upon the rear ends o-f the keys from which it receives its movement.. Therightlhand endl of the-key. coupler carries a roller54 Which.cooperates'With` aslot. ina driving; rack V43 guided by a stud 44 projecting from the frame of the machina` rlhe-driving rack is provi'dedvvith Vopposing racks-adapted to be thrownA into mesh alternately With'a gear 45 o-n a cam shaft 46V to rotatelthe shaft clockwise. The engagement of, thegracks Vwith the gear is effected andV maintainedby aspring 47, a springedraivn paw-148, a=iianger49on the rack, and a flange 5() on theiv frame, operating in the usual manner. ,y j

The cam shaft46(Fig. 9) extends through the -righthand side frame. A cam 51 fixed to this shaftcooperates,With a. spring-pressed Y pivotedimpressionfhammer supporting arm 521 curved toextend, through an opening in theprinter frame 53V (Fig.`13) into operative relation With ltheritem type Wheels 41. By means of this mechanism an impression is taken 'from the item type Wheels 41 upon an `issuing'stripvvduring each item entering operation.

@The right hand. end of the key coupler is provided vvith a trunnion 56 (Fig. 13) extending through the printer frame. Anarm 57 fixed to the trunnionV carries a spring dravvnpawvl '58 which ,cooperates With a ratch.-`v

l et 59 secured to a feed roller 60 for feeding the issuing stripY between the impressions made thereon. A spring tensioned roller 61 holds the strip in frictional engagement with the feed roller 60.A An inking ribbon 62 is provided `and may be fed by a` feed roller 63 which may-conveniently bedriven by a pavvl and ratchet (not shovvn) drivenV from the arm 57as usual, or in any preferred manner.

Y The amounts represented by the keys de-'i pressed are also entered in aftotalizermounted in a frame 65 (Figs. 1,-2 and 3) pivo-t'allyy and slidably supported on a rod 66 removably V:mounted in' brackets projectingV rear- Wardly from a front-cross bar 67 secured to theside frames.V Y Y Y vj f Y, The totalizer. elements (Figs-2and 3) fin.- cludel pinions 70 rigid with gearv Wheels 71 and ratchets 2 supported on a turnto-zero shaft 73; The` shaft -is provided Lvvith a groove to. cooperate With l spring-pressed paivls on the totalizer elementsto turn the totalizer to zero inthe usual manner..

The totalizer pinions170 are normally held Y disengaged from the actuators 39 by a cam 7 4 on the cam shaft 46, which cam 7 .4 cooperetes-With rollers 75 on a lever 76 mountedjon apivot pin 77 on the totalizer frame 65 but held'rigid With the frame by a pin 7 8. When a key is Adepressed the cam 74 is rotated'clock- Wisewhereby the lever 7.6 moves the totalizer pinions intomesh 'with the actuators.v

For the purpose of effecting transfers each totali'zer elementY is provided Withfa transferA trip projection 79 (Fig.l 3) adapted to engage a projection nose on al transfer `pavvl supporting arm 8O to move the same .out ofY supporting relation with respectto a `transfer pavvl 81, Whichmay then move into en- ,ga-gement` With the ratchet 72. VThis pavvl 81 ispivotally supported on a transfer lever 82 rocked by a cam 83 (Fig. 4) on the camshaft 46 during-each item enteringoperation vof the machine. 'j

The amount accumulated in the totalizer is ascertained bya printingoperation. Y For thispurpose, mechanism is provided for setting up total type Wheels 85 (Fig. 13) y.to print the amount in the tota-lizer. For this purposey alsothe totalizer has stepped disks 86 (Fig. 2) rigidWith gear Wheels 87 mounted .on a rod in the totalizer frame 65 and meshing with the gears 71 rigid with the totalizer pinions 70.

The total type Wheels S5 (Fig. 13) arelocated to the right of the printer frame 53 and are suitably supported therein and in a supplem-ental` frame 88. These Wheels are con'-l nected by a tube line 89 with gears 90 (Fig.

vvith segment-gears 93 connected by; aV tubev line 94 (Figs. 1, 4 and 9) with the right hand legs off yokes 95V having their other legsf96" extendedlinto` feelers 99r adapted to be, moved;

' an impression block 115.

into engagement with the steps on the disks 86 of the totalizer. The tube line is supported by a rod 98 supported in the printer frame and in a bracket 97 (Fig. 2) mounted on the front cross bar 67. The steps on the stepped disks 86 are so located that the type wheels 85 will be set in accordance with the amount in the totalizer when the feelers 99 of the yokes 95 are moved into contactwith said disks.

Also rigid with the segment-gears 92 (Fig. 9) are other segment-gears 100 which mesh with segment-gear levers 101 provided with hooks 102 supporting the upper ends of tension springs 103 attached to a rocking lever 104. 'The springs are normally restrained against moving the yokes 95 and total type wheels 85 by a bar 105 connected by a link 106 to said rocking lever 104. The lever 104 is rocked first clockwise and then counterclockwise by cams 107 secured on the driving shaft 108 driven by a gear 109 (Fig. 13) in mesh with a gear 110 driven by a` crank or motor, or any suitable means. As the rocking lever is moved clockwise to remove the bar 105 from the levers 101, the springs 103 are permitted to rock said levers and the tra-ins of segment-gears connected thereto until the feelers 99 contact with the disks 86 to set up the total type wheels 85 in accordance with the amount in the totalizer.

Impressions from the total type wheels 85 are taken upon the issuing strip 55 (Fig. 13) before referred to by a platen 112 carried by The block 115 also carries platens 113 and 114 cooperating with electros 116 and 117 respectively to print the matter shown at the top and bottom of a receipt shown in Fig. 10. The block 115 is flexibly supported on an arm 118 rigidly connected to a bell crank 119 carrying a roller at its lower end cooperating with a cam 120 secured to the shaft 108.

For the purpose of feeding the strip so that the printed total amount thereon moves past a severing knife 125. (Fig. 13) a feed roller 60 is driven by a ratchet 126 (Fig. 9) connected to the feed roller shaft, and adapted to be operated by a pawl 127 carried by a plate rigid withl a pinion 128 in mesh with a segment-gear 129 driven from a roller 130 carried by an extension on the rocking lever 104.

It is also desirable to print the totals on a detail strip 131 (Fig. 13) retained in the machine. The impression arm 132 for effecting this printing operation is driven by a link 133 connected to an arm 134 integral with the bell crank 119 before referred to. The detail strip 131 may be fed onto a receiving roll by any suitable means operable during a total printing operation and may include an arm 135 bifurcated to cooperate/with a pin 136 on a segment-gear lever 137.

Means is provided for returning the totalizer wheels to zero during a total printing operation. This means includes, as one of its elements, the segment-gear lever 137 (Fig. 13) which is connected by a short link 138 with the link 106. This segment-gear lever meshes with a gear 139 secured on a shaft 140 (Fig. 9) which freely supports the segmentgears 91, 92 and 100. Secured to the shaft 140 on the left side of the printer frame is a segment-gear 141 (Fig. 9) which meshes with a gear 142 carrying a spring-pressed pawl 143 cooperating with a ratchet 144 rigidly secured to a gear 145 in mesh with a gear 146. The gear 146 is mounted on a shaft 147 connected by a universal short shaft coupling 148 (Fig. 1) with the turn-to-zero shaft 73 of -.the totalizer. Upon operation of the machine, the clockwise movement of lever 104 (Fig. 9) causes the pawl 143 to ride freely over the ratchet 144, and upon the return movement of lever 104, the pawl and ratchet causes the shaft 147 to be rotated clockwise to reset the totalizer.

lfVhen resetting the totalizer wheels t0 zero, the transfer trip projections 79 (Fig. 3), as the totalizer wheels pass from 9 to 0, move the transfer pawl supporting arms 80, thus disengaging their shoulder from the transfer pawls 81. This would allow the transfer pawls 81 to swing downwardly and engage the ratchets 72 and move the totalizer wheels one space as the transfer levers 82 operate, were not a device provided to hold the transfer pawls 81 in their normal positions during a zeroizing and total printing operation.

This device consists of a shaft 64 ournaled in the totalizer frame 65 and having secured thereto a group of retaining arms 69 in alignment with the group of transfer pawls 81, but normally held out of contact therewith by a torsion spring 741. Also secured to this shaft 64 is an arm 68 (Fig. 1) cooperating with a cam 149 carried by the turn-to-zero shaft 73. During the first part of the rotation of the shaft 73, the cam 149 rocks the arm 68 and, consequently, the shaft 64 and arms 69 clockwise (Fig. 3), whereby the upper ends of the retaining arms 69 will contact, raise and hold the transfer pawls 81 in such positions that the shoulders on the transfer pawl supporting arms 80 may assume their normal positions after having been tripped by the transfer projections 79 during the turn-to-zero movements of the totalizer wheels. Near the end of the rotation of the turn-to-zero shaft 73, the cani 149 permits the arm 68, shaft 64 and retaining arms 69 to be rocked to their normal positions by the spring 741, thus permitting the transfer pawls 81 to be lowered to their normal positions, resting on the shoulders of the transfer pawl supporting arms 80.

This mechanism is substantially the same as that shown and described in applicants co-pending application, Serial No. 458,509`

Forthe purpose of counting the number of items or'amounts entered in the machine at any time beforethe totalis taken, counters are provided to. be actuated for each item or amount-,enteringoperation. rlhe frame 150 of the counters is shown in Figs. ,1, 5 and lli 9 supportedon the printer frame 53 by means ofbraeket plates162 as shown. The counters comprise separately operable counter wheelsVV 151 rigid Vwith ratchetwheels 152 y(Fig.t6) loosely mounted on afturn-.toszero shaft. 153 supported lin the counter frame.

- The counter. wheels are -actuated by pawls 1.54fandi1154 pivoted on an arm 155 pivotedy oni a 'study .163 carried by, the counter frame.

A link156 connected to said arm and to anV arm 157 fastened to they key-coupler trun- Vnion V56 operates said arm and pawls .during each .itemr operationl ofV the machine.V Any of the well knownand suitable transfer `mechanisms may be used to transfer from the lower orderwheel 151 to thehigher order wheel. 151. f

The counters (Fig.V 9.) areturned to Zero during each totalprinting operation by the turn-tolzero shaft 153 which is rotated by the segment-gear. 141, hereinbefore described, and intermediate gears 158 and 159 supported on studs on the counter. frame, which in turn rotate gear 160 secured to the turn-to-Zero shaft 153. The counter wheels 151 are provided with the usual retaining pawls 161.

InFig. 1 the totaliz'er is shown in its normal position, in which position it is kept during operations in which a plurality of Y' items are printed andtotaled, the result of which is shown in Fig. 12; When the totalizer is in this position the pawl 154 (Fig. .5) for the left. hand counter wheel 151 is rendered ineffective by a link 165, connected Vto an arm 166v pinned to a shaft 167 carrying an arm 168 moved clockwise (Fig. 2) by a' pin 169 on the totalizer frame 65 as the totalizer is rocked into engagement with its 39,- the `left hand side Vmember of the totalizerl frame .is provided with an aliner 171 (Figs.

1, and 2) adapted to` cooperate with notches in an aliner plate 172 suitably supported onintegral with the arm 1166 (Fig. 6.). connectedbyV the; link 1165 to the pawl 1154 for the right handcounter wheel151. The shifting of the totalizer tof-the right, as above mentioned, alsomoves thepin169 outofalignment with the arm 168 fast onthe-shaft 167. When the te'talizer is lrocked when` in'this posit-ionithe .pawl 1154 (Fig' 5)'is `disabled by the pin 80 and the left hand pawl '154is rendered effective because the pin 169 cannot strike Ythe arm 168.

In Fig. 4 an extra transfer camk83 is provided and the rollers on the lever 76 are eX- tended tothe right so that the totalizer will be rocked into engagement and the transfers effected when the totalizer is in either of its positions. o. Y

A push key L190 `(Figs. 1 .and 7) may be provided to set a type wheel to print the letter when processes of multiplication arek performed. This type wheel is carried on the outer tube of tube line 42 to which an arm 192 is connected.. This arm is operated by an arm 193 carried by the push key 190.

A spring 194 normally holds the pushkey in the position shown, in which position the letter M is not printed.r When a grand totalizer `is employed this keyoperates to throw out the grand ltotaliZer inthe usual mannerv through the link 191 and connections not shown in this application. Y

On the receipty strip illustrated in Fig. 10, there are printed five amounts .5077 with the letterl Mlin front of each one of them. At the bottom of this strip under the word ""lotal7 are the figures 11.50, VThis total represents .50 multiplied by 23. The reason for the .50 beingprinted in the same column in each case, is that in this preferred form, the totalizer is to be shiftedrelatively to the actuating racks, and since the ytype wheel gears are connected directly to the actuating racks, the type wheels are notl shifted. As the saine keys are operated three times with the totalizer in the normal position, and twice withit in its'rshifted position, the same actuating racks are operated each time, and the result accumulated. in the totalizer isV 11.50, and the amount printed for all live operations is ina single column.

The actual multiplying of c by 23 is. accomplished in the following manner:

Referring to Fig. 1, it will be noted that the machine is broken away, and that the full keyboard is not shown, the 10 key being the highest denominational order key shown; however, in applicants co-pending application, Serial No. 293,141, previously referred to in this application, there is disclosed a full keyboard having a capacity of 1e to $30.00.

Now to multiply 5095 by 23, the operator first makes sure that the totalizer is in the position shown in Fig. 1. He then depresses the 50 key three times, which accumulates into the totalizer 150, or in other words, $1.50. During this operation the key coupler 31 is oscillated three times, and the link 156 (Fig. 6) causes three movements of the pawl 115,4 associated with the units order counter wheel 151, whereby three steps of movement is given to this counter wheel so that it indicates 3. The operator then, by means of the handle 170, shifts the totalizer to the right one step and presses the 50c key two more times, thus adding into'the totalizer 1000, or $10.00. During this operation the key coupler 31 receives two oscillations, and the link 156 (Fig. 6) moves the pawl 154 associated with the Tens counter wheel 151 two times, thus giving two steps of movement to the Tens counter wheel 151 so that it shows 2. These two wheels 151 (Fig.

now indicate 23, showing that the multiplier was 23. The totalizer is now reset to Zero and the total printed, thus indicating in whole numbers 1150, or in decimals $11.50, as indicated by the receipt strip shown in Fig. 10. In the form disclosed in Figs. 14 to 17 the totalizer is not movable laterally, the multiplying being accomplished by providing a larger number of totalizer actuators than the number of digits in the largest amount that can be entered in the totalizer and by employing different combinations of actuators when performing processes of multiplication.

One of the segments actuated by the keys is shown at 200 (Figs. 17 and 18). Three such segments are employed, each in mesh with a pinion 201 fixed to a shaft 202 extending across the width of the machine. Pinions 203 are splined to the shafts 202 for rotation therewith and relatively lateral movement thereon. These pinions 203 are adapted to mesh with totalizer actuators 204 (Figs. 16 and 18) loosely mounted on a supporting rod 205. In the embodiment disclosed, five totalizer actuators are provided, with any three of which the pinions 203 and the totalizer may be engaged during each operation involving an entry of an amount in the totalizer. The units keys may therefore actuate the units, dimes or dollars totalizer wheels. Thus, it is possible to carry out a process of multiplication in which the multiplier may consist of three digits.

A U-shaped frame 210 (Figs. 15, 16 and 18) encloses the pinions 203, the legs of said frame being perforated to receive the shafts 202. Spacing sleeves 211 between the legs of said frame and said pinions hold the pinions Vin properly spaced relation with respect to each other and the frame. An aliner 212 is secured to said U-shaped frame 210, the alining edge of which is provided with three notches 213 normally in line with the units, tens Vand hundreds pinions 203 to permit the totalizer actuators 204 in mesh with said pinions to function. The other actuators are alined in home position regardless of the position of the frame 210. A handle 214 (Figs. 14 and 15) extending through a slot in the cabinet constitutes a means by which the pinions 203 may be positioned, the different poistions being indicated on the cabinet below the slot.

Counting means, involving counter wheels 164, is provided. The counter wheels mount- .ed in a frame 215 (Figs. 15 and 16) may be turned to zero by the same means as that used to turn the counter wheels 151 to zero, as shown in the first form (Fig. 9.) A counter actuating pawl 216 is flexibly supported on an arm 217 slidably and pivotally mounted on a spacing sleeve 218 on a rod 223 carried by forward extensions of the counter frame 215. Mounted on this rod 223 and held against lateral movement by the sleeve 218 is an arm 219 connected to the link 156 by a long pin 220 carried by the link 156 and extending through the arm 217. The link 156 is operated from the key coupler as in the first form (Fig. 6) and the pin 220 is long enough to engage the arm 217 in any one of the shifted positions of said arm. An aliner bar 221 secured to the counter frame is notched to cooperate with an aliner 222 on the arm 217 to properly aline the pawl 216 with the counter wheels 163.

A bar 225 secured to the frame 210 is pro- ,vided with a vertically extending arm 226 provided with a curved slot 227 to receive a pin secured in the arm 217. This pin is provided with a retaining flange 228 to hold the arms 217 and 226 against relative lateral movement. As the handle 214 is moved into the different positions indicated,'the arm 217 and pawl 216 are moved to select the counter wheel 164 appropriate to such position.

The manner in which 50 is multiplied by 23, when using the mechanism disclosed in the modified form shown in Figs. 14 to 18, will now be described.

In Fig. 15 the totalizer actuators 204 have been marked Units, Tens, Hundreds, Thousands, and l0-Thousands. The operator first makes certain that the handle 214 is in the 1 position (Fig. 14), he then depresses the 50e key three times. During this operation the differential segment 200 (Figs. 17 and 18) associated with the Tens actuator 204 is moved to the 5 position three tiines, 'and through the gear 201, shaft 20.2,"and pinion V203, vthe Tens actu- 'ator -204- is movedv three times, livefsteps at a time, thusadding into the totalizer byl means-of -thev Tens wheel, 15, and the total'izer wheelsA now stand as -ollows 2' Hundreds wheel 1, Tens wheel 5"1, and Units wheelfO. -D'uring this operation-the key c'oupler31 is given threero'scillations, and` the pawl 216 through the link 15,6 is raised andlowered Ythree times, and since this pawl is in cooperation with the Units counter wheel 164, 'that wheel is given three steps of' movement to indicate 3. The operator lnow shifts theV handle214 to the c2 position (Figi-14). In shiftingthehandle 214 from the l1 to th'e "2 position, the ramei210 is moved tothe left (Figs. 15 and 18), thus moving the pinions203 tothe left onestop, so that theyynowpengage-the Tens, Hundredsand Thousandsactuators 204.

- Vhat is claimed is: f -1. The combination of 'a totalizer, 'counter wheels for counting the number 'of actu-ations thereof, means for recording thefamountrbccumulated on the tot-alizer7 recording operating means, and means operated by said recording operating means for turning the counter wheels to zero. n

2. The combination of a totalizer, counter wheels for counting the number of actuations thereof, means for recording the amount accumulated on the totalizer, recording operating means, and means operated by the recording operating means for turning said totalizer and counter wheels to zero.

3. In a machine of the class described, the combination of denominational groups of amount keys; a differentially adjustable member associated with each group of keys and adapted to be operated thereby; a totalizer; actuators therefor, greater' in number than the number of adjustable members; connections intermediate said members and certain of said actuators, said connections including two sets of gears mounted on shafts to turn therewith; means for shifting one set of gears laterally relatively to said shafts to disconnect said gears from said certain actuators and to connect them, respectively, with certain other actuators, so that the same amount represented by the keys operated may be entered into different denominational orders of the totalizer.

4. In a machine of the class described, the combination of amount keys; differentially adjustable members operated thereby; a totalizer; actuators therefor; connect-ions intermediate said members and certain of said actuators, said connections including one set of gears meshing with said members and another set of gears meshing with the certain actuators, whereby the movement of said members under control of said keys is imparted to said certain actuators; means for shifting one set of gears laterally relatively to said actuators to disconnect them therefrom, and to connect them with other actuators, so that the same amount represented by the keys operated may be entered into different denominational orders of the totalizer; a plurality of counting elements; a single actuator therefor adapted to be shifted into operative relation with any of said counting elements by said gear shifting means, and means operated by depression of said keys to operate the counting element actuator.

5. The combination of a totalizer, actuators therefor, means laterally slidable to control the actuators to enter the same amounts in different denominations of the totalizer, means to engage the totalizer with and disengage it from the actuators, a plurality of counter wheels, operating means for the counter wheels shiftable with the 4slidable means to selectively operate the counter wheels, and connections between the totalizer and counter operating means t0 operate the counter operating means as the totalizer is being engaged with the totalizer actuators.

6. In a multiplying machine having means to retain the multiplier and means to accumulate the product of the numbers being multiplied, the combination of means to record the product, means to return the multiplier retaining means to zero, and a common drive to actuate the recording means and the returning means during the same cycle.

7 In a multiplying machine, means to multiply a multi-denominational multiplicand by a multi-denominational multiplier, a set of amount keys, means whereby the denominational value of said keys may be changed during such a multiplying operation, and a printing device to record the part of the product entered during each cycle of the 0peration.

8. In a multiplying machine, means to multiply a multi-denominational multiplicand by a multi-denominational multiplier, a set of amount keys, means whereby such a multiplying operation may be performed by depression of the amount keys, means wherebythe denominational value of said keys may be changed during the operation, and a printing device to record the part of the product entered by each depression of the amount keys during the operation.
